Some users have identified a problem, and NVIDIA has released a new version of their Firmware Update Tool to fix it.

Unfortunately, at system boot, some RTX 4090/4080 GPUs may produce blank screens. NVIDIA has detected and resolved this issue, however it will necessitate a firmware upgrade. A driver update would not help in this case because the issue occurs while the operating system is still loaded. As a result, it was necessary to install new firmware.

The firmware update is now available for download from NVIDIA's website. 

NVIDIA GPU UEFI Firmware Update Tool

To ensure compatibility with certain UEFI SBIOSes, an update to the NVIDIA GPU firmware may be required. Without the update, graphics cards in certain motherboards that are in UEFI mode could experience blank screens on boot until the OS loads. This update should only be applied if blank screens are occurring on boot.

The NVIDIA GPU Firmware Update Tool will detect whether the firmware update is needed, and if needed, will give the user the option to update it.

If you are currently experiencing a blank screen, please try one of the following workarounds in order to run the tool:

Ensure you are using the latest SBIOS from your motherboard vendor
Change boot mode from UEFI to Legacy/CSM
Boot using an alternate graphics source (secondary card or integrated graphics)
Once you have the tool downloaded, please run the tool and follow the on-screen instructions. Ensure all apps are closed before running the tool and make sure no OS updates are pending in the background. This tool can be used with Founders Edition as well as partner cards.
